Dr. Gaius Baltar

My favorite character on Battlestar Galactica is Dr. Gaius Baltar. He is a brilliant scientist who becomes Vice President. He is guilty of helping the Cylons attack the United Colonies. He loves, and is often controlled by, Number 6, an incorporeal woman, who is a product of his mind. He is also in love with Number 6's corporeal Cylon duplicate.

He suffers constantly from moral dilemmas and conundrums arising from his love for the Number 6's and his duty to help save the United Colony fleet from the Cylons. He is as prone to do the wrong thing as he is to do the right thing.

He is highly unpredictable.
